TANK-can.

Specification of Letters Patent.

. Patented Sept. 8, 1908.

Application filed February 21, 1908. Serial N01 416,991.

To" all whom it may concern:

Be it known that I, JOHN F. STREIB, of Avalon, Allegheny county, Pennsylvania, a citizen of the United States, have invented certain new and useful Improvements in Tank-Oars, of which the following is a full, clear, and exact description, reference being 'ha'd-to the accompanying drawings, in which like'characters refer to likeparts, and in which.

Figure 1 is a general view or elevation,

- partly in'section, of a tank car constructed in accordance with this invention; Fig. 2 is a plan view of a portion of the underfram, the tank being removed; Fig. 3 is a transverse section on the line 33 of Fig. 2 in direction of arrow, the bottom plate of the tank being also shown; Fig. 4 is a like View in an opposite direction on the line 44 of Fig. 2, the bottom plate of the tank being removed; Fig. 5 is a transverse section of the car through one of the bolsters of the underframe, the upper portion of the tank being removed; Fig. 5 1s a detail sectional plan of end of tank saddle and bolster showing member'tying or bracing saddle and bolster members to ether; .Figs. 6 and 7 are detail views of the olster end and tank stay tie plate forming a part of the invention, and Figs. 8, 9 and 10 are views similar to Figs. 2, 3 and 4, respectively, showing modificatlons in structure.

An object .of the present invention is to i provide a simple, durable and effective, as

well as an economical anchorage for tank cars in which the ends of the tank and carunderframe are free to expandand contract independently of each other.

A further object of the present invention is to provide detailed improvements in the car underframe.

Referring now in detail to the drawings, 1 represents the tank, 2 the center sills here shown as having upper and lower flanges, 3-

. are spaced apart by, and saddles 4 and bol- ,car as shown in Fig. 2.

Saddles 4 are builtstore 3 are tied together and braced by channel or dish-shapcd braces 3 the flanges of which are riveted to webs of the plates of saddles 4 and bolsters 3. Braces 3 may be of ordinary channel iron or may be formed by pressing. They are slightly inclined as shown in Figs. 5 and 5 At preferably a central location in the length of the center sills, formed by pressin or otherwise are upwardly extending integra saddle or cradle members 2 having concave upper faces which are riveted to the tank 1 or ottom plate 1. As shown in the draw? ings these saddle or cradle members 2? are formed on the upper flange of the center sills by upward deflection of said flanges. In the event of the center sills being-without 11 per flanges said saddles or cradles woul of .course, be formed by outward deflection of the sill webs.

5 are tie plates riveted tp the upper surfaces or flanges of the center sills Zand-extending from points at or near each end of the Tie plates 5 are notched at their inner ends at the point where the integral saddle or cradle members 2 are formed, so that each of the said plates extends for a distance between the integral saddle or cradle members. Each of the center sills 2 are further provided at the point where its integral sad le or cradle members 2 is formed with stiflening angles 6 which is also riveted to the inwardly projecting pertions of the tie plates 5. I

7 is a bolster end and tank stay tie plate perforated to receive one or more tank stays. and adapted to be riveted toend flanges of bolster diaphragms. Plates 7 are reinforced by ribs 7*.

In Figs. 8, 9 and 10 is shown slight modifications in the center sill structure therein. Angles 8 extend substantially the entire length of the center sills and abbreviated notched tie plates 9 are also provided. Stiifeners 10 and tie plates 11 are also providedto stiffen the center sill construction.

In other respects the structure is the same as that shown in Figs. 1 to 7, inclusive. As is customary saddles 4 are provided with wood blocks forming a'supportffor the tank ends which permits of contract on and expansion of the tank and-car frame independently of each other, a

Having th described my invention, the

following is what I claim as new therein and desire to secure by Letters Patent:

1. In a tank car, a pair of center sills having horizontal flan es deflected upwardly for a portion of their engths to form opposing concave saddle members.

2. In a tank car, a pair of center sills having horizontal flanges deflected upwardly for a portion of their lengths to form opposing concave saddle members and supplemental braces for said center sills adjacent to said saddle or cradle members.

3. In a tank car, a pair of center sills having horizontal flariges deflected upwardly for a portion of their lengths to form opposing concave saddle members and angle plates extending along said sills beneath said saddle or cradle members.

4. In a'tank car, a pair of center sills having horizontal flanges deflected upwardly for a portion of their lengths'to form opposing concave saddle members and angle plates riveted. to said center sills beneath said saddle or cradle members and a tie plate for i said center sills extending between said saddle or cradle members.

5. In a tank car, longitudinal center sills having horizontal flanges deflected upwardly at the longitudinal center of said sills to form saddle members. for the tank.

6. In a tank car, a pair of loi'igitudinal sills between the car bolsters having the lon gitudinal central portion of their upper flanges deflected to form opposing saddle members.

7. In a tank car, a pair of longitudinal sills between the car bolsters having the longitudinal central portion of their upper flanges deflected upwardly and riveted to the longitudinal central portion of the car tank.

8. In a tank car, a bolster comprising a pair of flanged diaphragms or plates, a ribbed or reinforced tie plate shaped to cover and tie together the outer and outer lower flanges of said diaphragms or plates.

9. In a tank car, a bolster comprising a pair of flanged diaphragms or plates, a tie plate shaped to cover the outer and outer lower flanges of said diaphragms or plates and perforated to receive a tank stay.

10. In a tank car, a bolster comprising a pair of flanged (,liaphragins or plates arid a tank stay shaped to cover the outer and outer lower flanges of said diaphragms or plates and thickened beneath said outer lower flanges.

The foregoing specification signed at Mo- Kees Rocks, Allegheny county, Pennsylvania, this fourteenth day of February, 1908. JOHN F. STREIB.
